I used to run my O.S. Green fitted with the FP 18 PSI actuator set to 26-27 PSI peak boost and about 22 PSI preload. The actuator will respond fine at your desired boost level(25 PSI). You'll be OK. This is preferable to running the 25 PSI unit with no preload IMO.

You'll probably have to tinker with the length of the actuator rod by chopping off 3/8" from the threaded end. The 18 PSI WGA responds really well to heavy preloading. Just ask Mikey@Spec-Ops.

Is the 71HTA going to be made available in BB format? I think that I read somewhere that FP would not be converting it to BB. Maybe I am wrong though.

I recall hearing similar. this was strictly a turbo based off cost vs performance for those looking for the next best thing to a stock turbo. however, I wonder if you requested it?

Best BBK Full dyno chart I've seen is 500 whp. If you have a link to a 550 whp BBK Full dyno chart, could you post the link here?

Mods aren't quite the same as the BBK FULL above, but it still seems like the HTA 71 falls short of the BBK FULL, to me it's in between the FP white and BBK FULL.

Impressive but 2.4L motor. Anything else at say 520+ whp? Not taunting. I just haven't seen it in all my searching on EvoM.

CT9A Silver beat me to it below and helped out with the AWD 71HTA graph I have not seen yet. Stoked to turn the wick up on this Friday!

And I agree. CBRD says 49lbmin and FP says 51lbmin but CBRD has better graphs to date. I really hope I can hit 500whp with the 71HTA I will be stoked.

Full Mod list as follows -

Stock Evo 9 Short Block
ARP Head Studs
Head decked
Valve Job
Super Tech Duals and Ti Retainers
Cosworth M3 Cams
AMS Intercooler
AMS LICP
Buschur UICP
FP71HTA (duh)
FP 25psi Wastegate
FP 84MM Intake
DW301 Fuel Pump
Milspec TB Seals
APS Twin Vent (Switching out to Tial QR on Friday)
Precision 1200CC (Switching out to FIC 1450 on Friday)
FIC Fuel Rail
FIC FPR
Spoolinup COP (Used Coils)
STM CrankCase Ventilation
MAP 02 Eliminator Dump Downpipe
Test Pipe
TurboXS RFL Ti

Im sure I am forgetting a few other things but you get the gist.

On a 2.0 I havent seen anything more than 500-505 ish, I dont think the turbo has the legs for much more then very very low 500's on a 2 liter, like the 500-510 dynojet range.

No ported or tubular exhaust mani, or modded intake mani?

That is what I was thinking. It seems to fall in line with most of the BBK Full HKS7460 graphs I have seen on the forum. Honestly if it falls anywhere between 480 and 500 Dyno Jet I will be really happy. Even at 430whp second gear is pointless on fat rubber on 9.5 rims. So much fun. If I can squeeze another 50whp and 50wtrq out of her this car will be an amazing stop light to stop light car.


No not yet. Mainfold is next on the list. Have a half size Koyo radiator and A/C deleted already so it is getting ready for a stock frame forward facing just for fun. :-)

Intake mani is stock as well. MAP Rev3 and a Boomba TB is next month.

I was talking about the BBK full lol, I think the HTA 71 could maybe hit 500 DJ under ideal conditions, but it's really a 450-480 awhp turbo depending on mods.

If Turbojunkie can hit 490 with the FP White you could maybe hit 500 maybe come close to 510 ish.

agreed your going to need intake mani and maby a exhaust mani to get close to 500 the fp white is a hair smaller but it was a built motor SD car with a magnus V5

My 71 hta numbers were with stock intake mani and exhaust mani, no porting coating, hks272 and a tbe(+ jmf intercooler, injen licp, muse dump, 84mm intake). Over the winter I have purchased a Skunk 2 intake manifold, and I am looking into S2's. I am also on SD. I will likely do tubular manifold before summer.

https://www.evolutionm.net/forums/ev...a71-3d-sd.html

You can see where Ive been with the turbo, if any thing my tuning experience underrates this turbo by a lot, and I am probably sacrificing some power with stock exhaust manifold and intake manifold there.


PS, I also had a FP WHITE!

Saying the white is a hair smaller is where I think this turbo is losing out in awareness. Its like saying the bbk full will make a hair more power than a bbk lite. There is a 5lbmin difference between the white and the 71hta. That is substantial. That is a 2lb bigger gap than an hta green and red.

71 hta is using the stock turbine wheel. you can only make so much power through a stock hotside. the 71 is virtually identical in potential to BBK lite. both turbos are pushing the limit of stock turbine wheel.

its a shame project bastard 550550BBK didnt bolt in other turbos like they planned. especially the HTAgreen. no one has ever done a back to back with those. project bastard had high compression. very important key to high HP small turbo setup. limited air flow should have small combustion chamber to fill to maximize the setup.
